You can search for the year on the marauders map now. Simply click on all users and search for the year you want, and all users in that year will be listed, together with their house (:

This is not possible since it would be too much work to create different cards for the different sites. Also, when someone gets banned for some reason, their card would have to be removed, which causes trouble with any possible collections. 

Please contact the chief editors of the newspapers on your site with this idea, they're always open for new ideas and inspiration (:

After discussing this topic it was considered that this is not possible. Backstories change approximately once an IG year, sometimes even more often. Every year at least the age is changed, sometimes also pictures, names and codes. This feature would mean a lot of work for the backstory team, since every small change would make the profile pop up again in admin section, and things like age changes or new friends in backstories don't need constant revision. It would put more pressure on the bs teams and not necessarily more order. The only positive thing it would do is sort out the inactive profiles, but the bs teams on the several sites already do a great job on that without the feature!
Furthermore, as it was already mentioned above, if the checkmark was visible for everyone, it could lead people to pester the the bs teams about getting it. If it was only visible for management it wouldn't make much sense, since they usually know when something is up with a backstory. 
So, although many of you wished for this, we decided that it's not a feature that we 're going to have on WoP. We're very sorry for any disappointment, but thank you a lot for all your input and ideas!
